Using an AACC treatement ContextCreation type application and I have defined CAV variable in one of the modules but the values are not being passed on to the application. All the modules have the pluggable connector enabled.
Is this a known behaviour or a bug?

I don't know how the AACC ContextCreation supposed to work. In terms of the CAVs, you have to administer the values through the main app on EPM. The main app has to have the CAV PDC enabled. On the EPM CAV admin page, you are supposed to see the aggregated list of variables from all the modules that the main app is using. So is this step done? I would need to take a look at the app trace.log to see what is happening.
